There is nothing "basic" about preserving your privacy in this age. I go to ridiculously great lengths to preserve my privacy. That entails using VMs with separate VPNs for every different thing I do on the internet to avoid cross-pollination between my online identities, that entails never taking my smartphone out of the house, that entails using burner phones, that entails accepting that I simply can't use an increasingly large number of services that are being gated by identity verification, which is now trying to be forced on being able to use a computer at all at the OS-level. It is an absolute pain in the ass to worry about this, and it's completely understandable why people give up, but that doesn't mean they actually want it to be this way. Privacy should be the default, not something you have to fight for.
